For several years now the international community has realized how important water is for the future of humanity and is taking positive action on its behalf.

The manifold pressures which it is subjected to - pollution, overconsumption etc. - are often the legacy of the past and a challenge to be met for the future.

Optimizing the water cycle, conserving this resource which is sometimes scarce locally, preserving water quality and assisting in water renewal are challenges for every continent. They can only be met if local authorities become involved, there where water is consumed and treated. Sustainable water management thus presupposes the involvement of all stakeholders who have a responsibility towards it, whether it be those who make the decisions, those who manage it or those who use it.
